CVE-2026-1997Network attack vector

Information disclosure via permissive EWS CORS policy

Published Feb 10, 2026 · Updated Feb 10, 2026

Origin validation error in HP OfficeJet Pro printer firmware allows remote attackers to access device resources through the EWS. The Embedded Web Server's CORS configuration accepts requests from unauthorized web origins instead of restricting resource access to trusted solutions. Exposure requires an administrator to enable and misconfigure CORS, which is disabled by default on Pro-class devices; the public record does not identify the specific resources exposed.
